| Abstract | High speed drive systems are often described at an operating point above the critical speed. Therefore, the resonance frequencies have to be passed twice (start up / run down). In the worst case, the strong vibrations at critical speeds can lead to self-destruction. Unbalanced rotors are the main cause for the self-excited vibrations. Over the past years, the focus of investigations [1] was laid on the improvement of the operating characteristics by using passive elements to guarantee stability of the system. However, the transition through the critical speed is still an unwanted high mechanical strain. In this paper, an innovative concept for rotary drives will be presented, which is able to compensate excessive vibrations or deflections actively. A permanent magnet excited synchronous motor (PMSM), which is able to generate motor torque and radial force simultaneously [2], with a large air gap is used. The capability of generating a highly dynamic and active control variable for the rotor position opens up new opportunities for drive applications. In this work, many different technical disciplines are combined, creating a truly mechatronic product. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
